Conference Background LDEC2007 is the fifth in a series of professional meetings conducted by those interested and practising in the fields of diabetes and endocrinology. Indeed the first three conferences ranged in duration from half a day to one day. They involved an increasing number of faculty and attracted more delegates. However, the fourth and fifth meetings expanded significantly, spann...

BACKGROUND Impact of body fat distribution on bone mineral content (BMC) and density (BMD) at different sites has not been studied in type-2 diabetes (T2DM). This study aimed to compare BMC and BMD in normal (BMI < 25 kg/m(2)) and increased BMI (BMI ≥ 25 kg/m(2)) T2DM patients with age and BMI matched normal controls, and evaluate the impact of lean mass and body fat distribution parameters on ...

OBJECTIVE To evaluate the influence of body composition on bone mass in children and adolescents. METHODS A cross-sectional study with 267 healthy students of both sexes (141 males and 126 females) aged 8 to 18 years. Weight, height, body mass index, lean mass, fat mass, fat mass index, body fat percentage, waist and hip circumferences, and waist-to-hip ratio were evaluated. Bone mass was ass...

BACKGROUND Total lean body mass (LEAN-tot) is one of the three major components of body weight. Its deterioration is a risk factor for frailty. Despite this, there are few studies examining the contribution of genetic factors. OBJECTIVE Our objective was to examine the contribution of genetic factors for LEAN-tot variation, including a genome-wide search for the genes. RESEARCH METHODS Dual...

The irregular morphology of single rock fracture significantly influences subsurface fluid flow and gives rise to a complex and unsteady flow state that typically cannot be appropriately described using simple laws. Yet the fluid flow in rough fractures of underground rock is poorly understood. Here we present a numerical method and experimental measurements to probe the effect of fracture roug...

This study determined whether a multivariate profile more effectively discriminated selected than non-selected elite youth Brazilian soccer players. This examination was carried out on 66 youth soccer players (selected, n = 28, mean age 16.3 ± 0.1; non-selected, n = 38, mean age 16.7 ± 0.4) using objective instruments. Multivariate profiles were assessed through anthropometric characteristics, ...

The purpose of this study was to determine the load which allows the highest peak power for resisted sprinting on a non-motorized treadmill and to determine if other variables are related to individual differences. Thirty college students were tested for vertical jump, vertical jump peak and mean power, 10 m sprint, 20 m sprint, leg press 1 RM, leg press 1 RM relative to body weight, leg press ...

The drag force on aggregates and partially sintered agglomerates is assessed using the lattice Boltzmann method (LBM) and accelerated Stokesian dynamics (ASD). Both methods have been compared in terms of accuracy and computational effort. It is shown that they give comparable results if all numerical parameters are controlled carefully. LBM requires a much higher computational effort, however, ...

We revisit the classical stability versus accuracy dilemma for the lattice Boltzmann methods (LBM). Our goal is a stable method of second-order accuracy for fluid dynamics based on the lattice Bhatnager-Gross-Krook method (LBGK). The LBGK scheme can be recognized as a discrete dynamical system generated by free flight and entropic involution. In this framework the stability and accuracy analysi...

The ability to measure body composition is critical for studying the physiological ecology of animals. This is particularly true for small mammals that have a high metabolic rate. We evaluated a nondestructive method of body composition analysis that would allow accurate assessment of body fat, body water, and lean mass. We used total body electrical conductivity (TOBEC) to estimate body compos...
